Sorry if this spec is somewhere, but wasn't able to find it. I'm somewhat familiar with the arduino Due, and am very interested in the possibility of swapping that out with a udoo! However, the application I'm looking at would "require" data transfer rates faster than the quoted 115200bps, and also cannot tolerate the USB lag (do to USB poll interval). As far as I can tell, the udoo has done away with the serial-to-USB conversion that the Due uses for the programming port. And the serial communication pins are just connect directly. Does this mean that the serial communications between the imx6 and Sam3x can be much faster than the ~256kbps that the Due seems to be limited to on the programming port? As long as you spec both ends to the same bps? Say 512k-1Mbps?
